Tax revenue from tobacco in 2012/13 £2.6 billion in VAT
so though the figure is higher when you compare how much revenue is actually lost through vaping.
current UK figures from ASH put UK smokers at 10 Million.
vapers are at reported 2 million.. However this does NOT show how many smoke and Vape. that figure i cant find.
can only etsimate but you could say thats a 10% reduction in smoking so 10% revenue loss would if my maths is right 260 million.
saying that the figures for cost to NHS and smoking related stuff ( cleanups of cig butts and everything else is more like 5billion ) which would put loss of revenue to the government even lower.
Just think the whole matter is another govt ploy to try and dismiss ecigs because of how much money they would lose but when you weigh up the number of ECIG only users ( as opposed to those who vape and smoke) and how much they are costing the govt compared to how much the NHS is saving its probably not a huge amount of actuall loss.
when you consider smoking has droped from national avergae of 40% down to around 22% in the UK in the past 30-40 years ( long before ecigs come along) i dont think the loss of revenue can ever be used as a genuine excuse.
